Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned jkense/agent-skills-wcag at 7fc6eec6ad.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill assesses the perceivability of color in web pages against Web Content Accessibility Guidelines (WCAG) 1.4.3 (Contrast (Minimum)). It identifies potential accessibility issues related to insufficient contrast between text and background colors, ensuring readability for users with visual impairments. The skill provides a detailed report outlining any violations found.

When to use it

  • Website Audits: Evaluate the color contrast of existing websites or web applications.
  • Design Reviews: Check designs before implementation to proactively address accessibility concerns.
  • Content Creation: Ensure new content, including images with text overlays, meets WCAG standards.
  • Accessibility Remediation: Identify specific areas needing improvement during an accessibility fix-up effort.

Key capabilities

  • WCAG 1.4.3 contrast ratio assessment
  • Detailed reporting of color contrast violations
  • Focus on text and background color pairs

Example prompts

  • "Analyze the color contrast of this webpage: [URL]"
  • "Check if the text color '#FFFFFF' on a background of '#000000' meets WCAG 1.4.3 requirements."
  • "Perform an accessibility audit focusing on color contrast for this design mockup."

Tips & gotchas

This skill requires providing either a URL or specific color codes to analyze. The results should be interpreted in the context of overall website accessibility, as color contrast is only one aspect of WCAG compliance.
